Alright, I had a neat experience. A few days ago I happened across an old book entitled Gospel Principles. This book is what the Church of Jesus Christ of Latter-Day Saints used in the 1970s to teach the principles of the gospel of Jesus Christ in a Sunday School class. Nowadays, in the same Sunday School class, we use a book called Gospel Principles. The newest edition went into use at the beginning of the year 2010. That was last year. A lot has changed in all those years. Even with the book, the cover and the pictures have changed almost 100%. But I got to thumbing through the book. It turns out that all the chapters of this manual are in the same order they were 40 years ago. What impressed me more was that the words in it were almost exactly the same as the newer version. There have been a few updates based on cultural and grammatical changes but really nothing has changed.
It surprised me at first, but as I thought about it, it makes a lot of sense. The gospel hasn't really changed at all. It's still exactly what Jesus Christ taught when He was on the earth. We could go back even further though. Christ taught the same teachings to prophets in the Old Testament and the Book of Mormon. And in our day, that gospel and all of the truths of it have been restored to the earth.
A lot has changed in the world in the past 40 years but some things will never change. Jesus Christ is our Savior. The Principles of His gospel are set in stone and will never be altered or adulterated within His restored church. Jesus Christ is at the head of our church and through His priesthood it is led.
